TIRE.

Application filed February 10, 1913. Serial No. 747,395.

To all whom it; may concern:

Be it known that I, JOHN ARCHIE Bon- LAND, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Tires, of which the following is a specification.

This invention relates to improvements in tires for wheels and has for its object to provide a tire having means whereby it may be fixedly secured to a wheel rim.

Another object of the invention is to provide a semi-solid rubber tire having a centrally disposed stiffening or reinforcing whereby the tire may more readily be held in fixed position relative to a wheel rim.

Still another object ofthe invention is to provide a tire having a cored out center andmeans whereby heated andexpanded air. in said core may escape.

With the above and other objects in View which will be more fully explained in the following specification, I have invented the device illustrated in the accompanying drawings in which Figure 1 is a transverse sectional view of a tire and wheel rim, Fig.2 is a side elevation of a spreader member, Fig. 3 is an edge view ofsaid member, and Fig. 4 is a sectional view taken on line A-A of Fig. 1.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings, in which 1 is a tire, formed preferably of rubber, but which may be made of any other suitable material, having its entire annular central portion cored out to form the bore 2, and having an annular channel 3 leading from said bore to the inner surface 4 of the tire.

Embedded in the inner portion of the tire adjacent the bore 2 and channel 3 and conforming to the contour of the walls thereof are a series of stiffening members 5, 6, 7 and 8 which are constructed preferably of a very stiff heavy canvas having the material from which the tire is chiefly made interspersed 15 of the rim flanges 16 and 17 whereby it is Specification of Letters Patent.

Patented J uly impossible for the tire to become accidentally disconnected from the rim.

Located in thechannel 3 are a series of spring spreader members 18 having openings 20 arid 21 for accommodation of the tubes 11. These spreading members normally force the flanges 19 and 22 apart whereby said parts are held seated against the flanges of the rim. The tubes 11 are provided with openings 23 whereby there may be. a .free' passage of air in and from the bore 2 in the tire. If necessary openings 24 may be provided in the flange 17 adjacent the tubes 11 whereby air may pass from the tire.

While this tire is designed especially for racing and other rapid running automobiles where friction will cause the expansion of air in the bore 2 and, ordinarily would cause such an expansion of the air, a bursting of the tire would often occur and the great-- strain in taking curves would often cause the tlre to become loosened from the wheel rim, yet it is equally adaptable for pleasure cars and especially for heavy trucks where a very I 1.
